Kanto

Oshima Island

The greatest highlight of Izu Oshima is its variety of tourist attractions, starting with Mt. Mihara.

Mt. Mihara, standing 758 meters high, occupies the center of the island. Of the several active volcanoes in Japan, this is known particularly for the eruption of basaltic magma. Its lava fountains have been deified since antiquity as gojinka-sama. The caldera at the summit of the cone commands a view 300 meters in diameter and more than 200 meters deep into the volcanic crater.
